Single Node OpenShift

Imagine having a fully-fledged OpenShift cluster at your fingertips, without the complexity or costs associated with deploying it across multiple machines. That’s where Single-Node OpenShift (SNO) comes in a simplified deployment that lets you run OpenShift on a single machine, backed by Red Hat’s comprehensive documentation for various platforms. In this post, we’ll dive into setting up SNO clusters on both AWS and VMware, exploring the benefits of a compact, self-contained environment. With SNO, you can forget about the overhead of managing multiple nodes and focus on what matters most developing, testing, or deploying your applications. And when it comes to storage, I’ll show you how to unlock the potential of your local disks using the Local Storage Operator, turning them into a reliable storage class for your on-premises environment.

I’ll walk you through the steps required to set up a single-node cluster on both AWS and VMware vSphere. I’ll cover the specific requirements for each platform.

• AWS: Setting up a single-node OpenShift cluster on AWS includes the steps such as configuring Route 53 for DNS, ensuring the IAM user has necessary permissions, obtaining the installation program, and installing the cluster by providing configuration details in an install-config.yaml file.
• VMWare vSphere: Setting up a single-node OpenShift cluster on VMware vSphere includes steps such as creating the DNS records, creating the administration host to prepare the ISO (CD/DVD image), generating the discovery ISO with the Assisted…
